Description
~08V2~6 Type Ib The present invention relates to certain new 6-oxo-pyrimidi~yl(t~iono)(thiol)-phosphoric(phosphonic) acid esters and ester-amides, to a process ~or their pre-paration an~ to their use as arthropodici~es, especially as insecticides and acaricides.
It is already known that certain O,O-dialkyl-O-pyrimidinyl-thionophosphoric acid esters, for example 0,0-diethyl-0-L2-methylthio- or 2-isopropyl-6-methyl-pyrimidin-4-yl ]-thionophosphoric acid ester, have in-secticidal and acaricidal properties (see Swiss Patent Specification 321,868 and German Patent Specification 910,652).
The present invention now provides, as new compounds, the 6-oxo-pyrimidinyl(thiono)(thiol)-phosphoric(phos-phonic) acid esters and ester-amides of the general formula X /OR
4 ~P \ 1 R I R (I) in which R represents alkyl, : 20 Rl represents alky~ alkoxy, alkylthio,alk-yl-amino or phenyl, R2 represents hydrogen, alkyl, alkoxy, alkylthio or alkylamino R3 represents alkyl or alkenyl, R4 represents hydrogen, alkyl or halogen and X represents oxygen or sulphur.
.; , ~
~ Le A 17 268 - 2 -.. ~.. .,, , -~08~Z26 The present compounds have been found to posses.s an excellent insecticidal and acaricidal action.
Preferably, R represents straight-chain or branched alkyl with 1 to 4 carbon atoms, R1 represents straight-chain or branched alkyl with 1 to 3 carbon atoms or straight-chain or branched alkoxy, alkylthio or mono-alkylamino, each with 1 to 4 carbon atoms, or represents phenyl, R represents hydrogen, straight-chain or branched alkyl with 1 to 4 carbon atoms, straight-chain or branched alkoxy or alkylthio, each with 1 to 3 carbon atoms, or dialkylamino with 1 to 3 carbon atoms per alkyl group, R3 represents alkyl or alkenyl, each with up to 4 carbon atoms, R4 represents hydrogen, chlorine, bromine, methyl or ethyl, and X represents sulphur.
The invention also provides a process for the pre-paration of a 6-oxo-pyrimidinyl(thiono)(thiol)-phosphoric (phosphonic) acid ester or ester-amide of the formula (I) in which (a) a (thiono)(thiol)-phosphoric(phosphonic) acid ester halide or ester-amide halide of the general formula RO "

The following may be mentioned as individual examples of the industrially readily accessible alkyl halides and alkenyl halides (V): methyl iodide, methyl bromide, ethyl bromide, ethyl iodide, n-propyl bromide, n-butyl bromide, allyl bromide and crotyl bromide.
The process for the preparation of the compounds according to the invention is preferably carried out in Le A 17 268 - 16 -the presence of a suitable solvent or diluent. V;rtually all inert organic solvents can be used for this purpoC;e~
especially aliphatic and aromatic, optionally chlorinated, hydrocarbons, such as benzene, toluene, xylene, benzine, methylene chloride, chloroform, carbon tetrachloride and chlorobenzene; ethers, for example diethyl ether, dibutyl ether and dioxan; ketones, for example acetone, methyl ethyl ketone, methyl isopropyl ketone and methyl isobutyl ketone; and nitriles, such as acetonitrile and propio-nitrile.
All customary acid-binding agents can be used as acid acceptors. Alkali metal carbonates and alkali metal alcoholates, such as sodium carbonate and potassium carbonate, sodium methylate and ethylate and potassium methylate and ethylate, have proved particularly suitable, as have aliphatic, aromatic or heterocyclic amines, for example triethylamine, trimethylamine, dimethylaniline, dimethylbenzylamine and pyridine.
The reaction temperature can be varied within a fairly wide range. In general, the reactionis carried out at from 10 to 120C, preferably at from 35 to 60C.
The reaction is in general allowed to take place under normal pressure.
To carry out process variant (a), the starting materials are preferably employed in equimolar amounts. An excess of one or other reactant produces no significant advantages. The reactants are in general brought together ~ in one of the stated solvents and are stirred for one or : more hours, in most cases at an elevated temperature, in order to complete the reaction.
Le A 17 268 - 17 -. .
~O~OZZ6 Therearter an organic solvent;, for example toluene, is added to the reaction mixture and the organic phase is worked up in accordance with customary methods, by washing, drying and distilling off the solvent.
In process variant (b), the alkyl halide or alkenyl halide is preferably employed in 10-15% stoichiometric excess. The reaction is carried out, and the mixture worked up, as described for process variant (a).
The new compounds are often obtained in the form of oils which in most cases cannot be distilled without decom-position but can be freed from the last volatile con-stituents by so-called "slight distillation", that is to say by prolonged heating under reduced pressure to moderately elevated temperatures, and can be purified in this way.
They are characterised by the refractive index. Some compounds are obtained in a crystalline form having a sharp melting point.
As already mentioned, the 6-oxo-pyrimidinyl-(thiono) (thiol)-phosphoric(phosphonic) acid esters and ester-amides according to the invention are distinguished by an ex-cellent insecticidal and acaricidal activity. They are active against plant pests, pests harmful to health and pests of stored products and, in the veterinary medicine field, against ectoparasites. They combine a low phyto-toxicity with a good action against sucking and biting insects and mites.
For this reason, the compounds according to the inven-tion can be employed successfully as pesticides in plant protection as well as in the hygiene field, the field of protection of stored products and the veterinary field.
Le A 17 268 - 18 -108~3ZZ6 The active compounds are well tolerated by plan~s, have a favourable level of toxicity to warm-blooded anima:ls, and can be used for combating arthropod pests, especiall;y insects and arachnids, which are encountered in agri^ulture, in forestry, in the protection of stored products and of materials, and in the hygiene field. They are active against normally sensitive and resistant species and against all or some stages of development. The above-mentioned pests include:
from the class of the Isopoda, for example Oniscus asellus, Armadillidium vulgare and Porcellio scaber; from the class of the Diplopoda~ for example Blaniulus guttu-latus; from the class of the Chilopoda, for example Geophilus carpophagus and Scutigera spec.; from the class of the Symphyla, for example Scutigerella immaculata;

emulsion concentrates, seed-treatment powder~, natur~l and synthetic materials impregnated with active compound, very fine capsules in polymeric substances and in coating compositions for use on seed, and formulations used with burning equipment, such as fumigating cartridges, fumi-gating cans and fumigating coils, as well as ULV cold mist and warm mist formulations.
These formulations are produced in known manner, for example by mixing the active compounds with extenders, that is to say, liquid or solid or liquefied gaseous diluents or carriers, optionally with the use of surface-active agents, that is to say, emulsifying agents and/or dispersing agents and/or foaming agents. In the case of ; the use of water as an extender, organic solvents can, for example, also be used aæ auxiliary solvents.
As liquid diluents or carriers, especially solvents, there are suitable in the main, aromatic hydrocarbons, such as xylene, toluene, benzene or alkyl-napthalenes, chlorinated aromatic or chlorinated aliphatic hydrocarbons, such as chlorobenzenes, chloroethylenes or methylene chloride, aliphatic or alicyclic hydrocarbons, such a8 cyclohexane or paraffins, for example mineral oil fractions, alcohols, such as butanol or glycol as well as their ethers and esters, ketones, such as acetone, methyl ethyl ketone, methyl isobutyl ketone or cyclohexanone, or strongly polar solvents, such as dimethylformamide and dimethylsulphoxide, as well as water.
By liquefied gaseous diluents or carriers are meant ; liquids which would be gaseous at normal temperature and under normal pressure, for example aerosol propellants, such as dichlorodifluoromethane or trichlorofluoromethane.

~oso226 As solid carriers there are preferably used ground natural ~inerals, such as kaolins, clays, talc, chalk, quartz, attapulgite, montmorillonite or diatomaceous earth, and ground synthetic minerals, such as highly dispersed - 5 silicic acid, alumina and silicates.
Preferred examples of emulsifying and foam-forming agents include nonionic and anionic emulsifiers, such as polyoxyethylene-fatty acid esters, polyoxyethylene-fatty alcohol ethers, for example alkylaryl polyglycol ethers, alkyl sulphonates, alkyl sulphates and aryl sulphonates as well as albumin hydrolysis products; and preferred examples of dispersing agents include lignin sulphite waste liquors and methylcellulose.
Adhesives such as carboxymethylcellulose and natural and synthetic polymers in the form of powders, granules or latices, such as gum arabic, polyvinyl alcohol and polyvinyl acetate, can be used in the ~ormulations.
It is possible to use colorants such as inorganic pigments, for example iron oxide, titanium oxide and Prussian Blue, and organic dyestuffs, such as alizarin dyestuffs, azo dyestuffs or metal phthalocyanine dye-stuffs, and trace nutrients, such as salts of iron, manganese, boron, copper, cobalt, molybdenum and zinc.
The formulations in general contain from 0.1 to 95 per cent by weight of active compound, preferably from 0.5 to 90 per cent by weight.
, The active compounds according to the invention may be used in the form of their formulations of the types that are commercially available or in the use forms prepared from these formulations.
The active compound content of the use forms pre-Le A 17 268 - 23 -lC~80Z;~6 pared from the formulations of the types that are commer-cially available can vary within wide ranges. The active compound concentration of the use forms can be from 0.0000001% to 100% by weight of active compound, preferably from 0.01% to 10% by weight.
The compounds are employed in a customary manner appropriate for the particular use forms.
When used against pests harmful to health and pests of stored products, the ac~ive compounds are distinguished by an excellent residual activity on wood and clay as well as a good stability to alkali on limed substrates.
The present invention also provides an arthropod-cidal composition containing as active ingredient a compound of the present invention in admixture with a solid or liquefied gaseous diluent or carrier or in ad-mixture with a liquid diluent or carrier containing a surface-active agent.
The present invention also provides a method of combating arthropods (especially insects or acarids) which comprises applying to the arthropods, or to a habitat thereof,a compound of the present invention alone or in the form of a composition containing as active ingredient a compound of the present invention in admixture with a diluent or carrier.
The present compounds also show a nematicidal activity.
The present invention therefore provides a method of com-bating nematodes which comprises applying to the nematodes, or to a habitat thereof, a compound of the present in-vention alone or in the form of a composition containing as active ingredient a compound of the present invention Le A 17 268 - 24 -in admixture with a diluent or carrier.
The present invention further provides crops pro-tected from damage by arthropods by being grown in areas in which immediately prior to and/or during the time of the growing a compound of the present invention was applied alone or in admixture with a diluent or carrier.
It will be seen that the usual methods of providing a harvested crop may be improved by the present invention.

Example 1:
SCH
(C2N50)2P-(~_CH3 (1) A mixture of 17.2 g (0.1 mol) of 1,6-dihydro-4-hydroxy-l-methyl-2-methylthio-6-oxo-pyrimidine, 20.7 g tO.15 mol) of potassium carbonate and 18.8 g (0.1 mol) of O,O-diethyl-thionophosphoric acid diester chloride was stirred for 12 hours at 45C. The reaction mixture was then poured into 400 ml of toluene and washed twice with 300 ml of water at a time. The toluene solution was dried over sodium sulphate and evaporated in vacuo. The residue was triturated with petroleum ether and the product was filtered off after it had crystallised. In this way, 11.3 g (35% of theory) of 0,0-diethyl-0-[1,6-dihydro-1-methyl-2-methylthio-6-oxo-pyrimidin-4-yl]-thionophosphoric acid ester were obtained in the form of colourless crystals of melting point 74C.
Example 2:
(C2N5o)2p-o ~ CN3 (2) 15.6 g (0.11 mol) of methyl iodide were added to a mixture of 26.4 g (0.1 mol) of 0,0-diethyl-0-[6-hydroxy-pyrimidin-4-yl]-thionophosphoric acid ester, 20.7 g (0.15 mol) of potassium carbonate and 300 ml of aceto-nitrile. The reaction mixture was stirred for a further 3 hours at 45 C and was then poured into 400 ml of toluene.
Le A 17 268 - 38 -1080~26 The toluene solution was washed twice with 300 ml of water at a time and was dried over sodium sulphate. The solvent was then stripped off in vacuo and the residue was subjected to slight distillation. After trituration with petroleum ether, the crystalline product was filtered off.
17 g (62% of theory) of 0,0-diethyl-0-[1,6-dihydro-1-methyl-6-oxo-pyrimidin-4-yl]-thionophosphoric acid ester were thus obtained in the form of a colourless powder of melting point 66C.

The following may be mentioned as individual examples of the industrially readily accessible alkyl halides and alkenyl halides (V): methyl iodide, methyl bromide, ethyl bromide, ethyl iodide, n-propyl bromide, n-butyl bromide, allyl bromide and crotyl bromide.
The process for the preparation of the compounds according to the invention is preferably carried out in Le A 17 268 - 16 -the presence of a suitable solvent or diluent. V;rtually all inert organic solvents can be used for this purpoC;e~
especially aliphatic and aromatic, optionally chlorinated, hydrocarbons, such as benzene, toluene, xylene, benzine, methylene chloride, chloroform, carbon tetrachloride and chlorobenzene; ethers, for example diethyl ether, dibutyl ether and dioxan; ketones, for example acetone, methyl ethyl ketone, methyl isopropyl ketone and methyl isobutyl ketone; and nitriles, such as acetonitrile and propio-nitrile.
All customary acid-binding agents can be used as acid acceptors. Alkali metal carbonates and alkali metal alcoholates, such as sodium carbonate and potassium carbonate, sodium methylate and ethylate and potassium methylate and ethylate, have proved particularly suitable, as have aliphatic, aromatic or heterocyclic amines, for example triethylamine, trimethylamine, dimethylaniline, dimethylbenzylamine and pyridine.
The reaction temperature can be varied within a fairly wide range. In general, the reactionis carried out at from 10 to 120C, preferably at from 35 to 60C.
The reaction is in general allowed to take place under normal pressure.
To carry out process variant (a), the starting materials are preferably employed in equimolar amounts. An excess of one or other reactant produces no significant advantages. The reactants are in general brought together ~ in one of the stated solvents and are stirred for one or : more hours, in most cases at an elevated temperature, in order to complete the reaction.
Le A 17 268 - 17 -. .
~O~OZZ6 Therearter an organic solvent;, for example toluene, is added to the reaction mixture and the organic phase is worked up in accordance with customary methods, by washing, drying and distilling off the solvent.
In process variant (b), the alkyl halide or alkenyl halide is preferably employed in 10-15% stoichiometric excess. The reaction is carried out, and the mixture worked up, as described for process variant (a).
The new compounds are often obtained in the form of oils which in most cases cannot be distilled without decom-position but can be freed from the last volatile con-stituents by so-called "slight distillation", that is to say by prolonged heating under reduced pressure to moderately elevated temperatures, and can be purified in this way.
They are characterised by the refractive index. Some compounds are obtained in a crystalline form having a sharp melting point.
As already mentioned, the 6-oxo-pyrimidinyl-(thiono) (thiol)-phosphoric(phosphonic) acid esters and ester-amides according to the invention are distinguished by an ex-cellent insecticidal and acaricidal activity. They are active against plant pests, pests harmful to health and pests of stored products and, in the veterinary medicine field, against ectoparasites. They combine a low phyto-toxicity with a good action against sucking and biting insects and mites.
For this reason, the compounds according to the inven-tion can be employed successfully as pesticides in plant protection as well as in the hygiene field, the field of protection of stored products and the veterinary field.
Le A 17 268 - 18 -108~3ZZ6 The active compounds are well tolerated by plan~s, have a favourable level of toxicity to warm-blooded anima:ls, and can be used for combating arthropod pests, especiall;y insects and arachnids, which are encountered in agri^ulture, in forestry, in the protection of stored products and of materials, and in the hygiene field.

emulsion concentrates, seed-treatment powder~, natur~l and synthetic materials impregnated with active compound, very fine capsules in polymeric substances and in coating compositions for use on seed, and formulations used with burning equipment, such as fumigating cartridges, fumi-gating cans and fumigating coils, as well as ULV cold mist and warm mist formulations.
These formulations are produced in known manner, for example by mixing the active compounds with extenders, that is to say, liquid or solid or liquefied gaseous diluents or carriers, optionally with the use of surface-active agents, that is to say, emulsifying agents and/or dispersing agents and/or foaming agents. In the case of ; the use of water as an extender, organic solvents can, for example, also be used aæ auxiliary solvents.
As liquid diluents or carriers, especially solvents, there are suitable in the main, aromatic hydrocarbons, such as xylene, toluene, benzene or alkyl-napthalenes, chlorinated aromatic or chlorinated aliphatic hydrocarbons, such as chlorobenzenes, chloroethylenes or methylene chloride, aliphatic or alicyclic hydrocarbons, such a8 cyclohexane or paraffins, for example mineral oil fractions, alcohols, such as butanol or glycol as well as their ethers and esters, ketones, such as acetone, methyl ethyl ketone, methyl isobutyl ketone or cyclohexanone, or strongly polar solvents, such as dimethylformamide and dimethylsulphoxide, as well as water.
By liquefied gaseous diluents or carriers are meant ; liquids which would be gaseous at normal temperature and under normal pressure, for example aerosol propellants, such as dichlorodifluoromethane or trichlorofluoromethane.

Preferred examples of emulsifying and foam-forming agents include nonionic and anionic emulsifiers, such as polyoxyethylene-fatty acid esters, polyoxyethylene-fatty alcohol ethers, for example alkylaryl polyglycol ethers, alkyl sulphonates, alkyl sulphates and aryl sulphonates as well as albumin hydrolysis products; and preferred examples of dispersing agents include lignin sulphite waste liquors and methylcellulose.
Adhesives such as carboxymethylcellulose and natural and synthetic polymers in the form of powders, granules or latices, such as gum arabic, polyvinyl alcohol and polyvinyl acetate, can be used in the ~ormulations.
It is possible to use colorants such as inorganic pigments, for example iron oxide, titanium oxide and Prussian Blue, and organic dyestuffs, such as alizarin dyestuffs, azo dyestuffs or metal phthalocyanine dye-stuffs, and trace nutrients, such as salts of iron, manganese, boron, copper, cobalt, molybdenum and zinc.

Example 1:
SCH
(C2N50)2P-(~_CH3 (1) A mixture of 17.2 g (0.1 mol) of 1,6-dihydro-4-hydroxy-l-methyl-2-methylthio-6-oxo-pyrimidine, 20.7 g tO.15 mol) of potassium carbonate and 18.8 g (0.1 mol) of O,O-diethyl-thionophosphoric acid diester chloride was stirred for 12 hours at 45C. The reaction mixture was then poured into 400 ml of toluene and washed twice with 300 ml of water at a time. The toluene solution was dried over sodium sulphate and evaporated in vacuo. The residue was triturated with petroleum ether and the product was filtered off after it had crystallised. In this way, 11.3 g (35% of theory) of 0,0-diethyl-0-[1,6-dihydro-1-methyl-2-methylthio-6-oxo-pyrimidin-4-yl]-thionophosphoric acid ester were obtained in the form of colourless crystals of melting point 74C.
Example 2:
(C2N5o)2p-o ~ CN3 (2) 15.6 g (0.11 mol) of methyl iodide were added to a mixture of 26.4 g (0.1 mol) of 0,0-diethyl-0-[6-hydroxy-pyrimidin-4-yl]-thionophosphoric acid ester, 20.7 g (0.15 mol) of potassium carbonate and 300 ml of aceto-nitrile. The reaction mixture was stirred for a further 3 hours at 45 C and was then poured into 400 ml of toluene.
Le A 17 268 - 38 -1080~26 The toluene solution was washed twice with 300 ml of water at a time and was dried over sodium sulphate. The solvent was then stripped off in vacuo and the residue was subjected to slight distillation. After trituration with petroleum ether, the crystalline product was filtered off.
17 g (62% of theory) of 0,0-diethyl-0-[1,6-dihydro-1-methyl-6-oxo-pyrimidin-4-yl]-thionophosphoric acid ester were thus obtained in the form of a colourless powder of melting point 66C.
